SG (B) 10, 11 series non -packaged H -class dry power transformers

This product is based on the use of DuPont NOMEX paper as the basic system of Wankong Company. With reference to the high -performance, high -safety, environmentally friendly dry transformers independently developed by Mora Technology in Germany. Environment. Such as airports, power plants, metallurgical operations, hospitals, high -rise buildings, shopping malls, residential sets, and special environments such as petrochemical, nuclear power plants, and nuclear submarines.

Performance characteristics

The heat dissipation conditions are good, the heat life is long, and the overload capacity is extremely strong. With 120%of the long -term overload, there is no compulsory wind and cold under IP45 conditions, and can run over a long period of load.

The high safety and burning resistance performance is produced at 800 ° C high temperature for a long time.

A strong anti-heat strike capacity (immediately fill the load immediately at -50 ° C)

100 % waterproof and sealing, excellent water hate and moisture resistance.

The unique coil structure and strong field calculation make the product almost unpopular.

Losses are low, the energy saving effect is significant. Compared with the SC9 series dry transformers, the average air load loss decreases by 20%on average, and the load loss decreases by 5%.

After the life period, the insulation material can be easily separated from the copper line, and it can not pollute the environment.

Structural features

The unique porcelain insulation mechanism uses the Mora company insulating barrel and high -frequency ceramic pads, which will never deform.

The high and low voltage coils are first used with NOMEX insulation materials, and the H -level insulation of the special formula is multiple times through the VPI vacuum compression equipment. After multiple baking, the external high -strength insulation material is sealed and cured at high temperature. The high -voltage coil adopts a continuous structure with high mechanical strength and good heat dissipation conditions.

The iron core is made of imported high -quality high -quality magnetic performance silicon steel sheets. It steps forward 45 ° full -slashing structure. The winding and iron core uses elastic fixed devices to make the transformer have lower air load loss and noise. The surface of the iron core is treated with special crafts. The iron core is appropriately clamped by the pull screw, and the upper and lower clamps are connected by the plate and fixed with the base and winding. The winding is fixed by elastic pads. The buffer structure can reduce the vibration level of the winding and reduce noise.

The wire terminal is fixed in the upper part of the winding, and the middle part of the joint winding is divided. The low -voltage line terminal is the plate -type conductive row, and cold pressure welding is used.
